Froth flotation is the use of the physical and chemical properties of the surface of the ore, the use of chemical separation of useful ore. In the process of froth flotation, useful minerals are separated by floating them in the foams, and the way of keeping gangue minerals in the pulp is called positive flotation, while the way of floating gangue minerals in the foam is called reverse flotation.>
Froth flotation is the most widely used phosphate ore separation process. Because of the nature of the phosphate ore, such as mineral types and content, disseminated particle size, its separation difficulty and flotation types varies. Phosphate ore is divided into siliceous phosphorite, calcareous phosphorite, and siliceous phosphorite according to the chemical composition of the minerals.The froth flotation types differ from different types of phosphate ore greatly. The following is a brief introduction to 5 common types of phosphate ore forth flotation process.
Froth flotation process can be divided into one stage froth flotation and two stages froth flotation (also known as stage froth flotation). So how do you choose the froth flotation process according to the stage? Generally, the selection of froth flotation stages mainly depends on the embedding features of useful minerals.
Flotation of non-sulfide minerals is more difficult than that of sulfide minerals. The main reason is that non-sulphide ores usually have high water solubility, and the useful minerals and gangue minerals are usually of similar types, with a small difference in surface properties.
